The purpose of this study was to investigate characteristics of past injuries of female university soccer players in comparison with injuries in male university soccer players.
We investigated past injuries of female players (n=32) and male players (n=24) . A past injury was defined as any injury sustained during soccer that required admission to a team doctor, medical attention or absence from practices or games for more than seven days.
The most frequent injury was Joint Injuries in both female and male players. High occurrence of overuse injuries of lower leg was most apparent in the female players. The 32 female players had experienced 144 injuries, or 4.5 injuries per player, and the 24 male players had suffered 85 injuries, or 3.5 injuries per player. The numbers of injuries per player of female players were 1.3 times higher than the male players. Also, the incidence of injury was 0.64 (injury/player/year) in female players, and 0.27 (injury/player/year) in male players. The incidence of injury of female players was significantly larger than that of male players.
We conclude that the prevention and care of overuse injuries in lower leg is very important for female succor players.

We analyzed the differences between responder and non-responder groups using Choyoto for hand eczema. In 7 cases the drug was effective, and in 6 cases it was not. Most patients in the effective group had white-complexioned skin, and the eczema tended to localize on the hands. In contrast, most patients in the non-effective group had with sleep difficulties and/or a smoking habit. In addition, they showed marked symptoms of Oketsu such as dark red gingiva, indicating that many of the non-effective hand eczema cases had elevated Oketsu scores. It was shown that objective and subjective symptoms could be indicators for the choosing of Choyoto for hand eczema treatment.

Background
According to the state of the world's children 2006, 28% of children under five years of age in sub-Sahara Africa are malnourished, which has serious effects on these children's health and lives.
Extensive research has been conducted on child malnutrition in a variety of developing countries. These studies have established scientific indexes to lead and coordinate international action to assist the needy. Central African Republic, however, has been a blind spot. Therefore, the present study was conducted in order to clarify the nutritional status and associated factors of 6 to 24-month-old children in the district of Boy-rabe, Bangui, Central African Republic.
Methods
Participants were mothers with children aged 6-24 months who visited either a government-run clinic or the NGO-run clinic, Amis d'Afrique, between August 26th and September 16th of 2006. Mothers were interviewed using a structured questionnaire and measurements of the children's weight and length were collected. Weight, length, and age data were compared with child growth standards proposed by the WHO to calculated z-scores for evaluatinglength-for-age (wasting), weight-for-length (stunted growth), and weight-for-age (underweight). The following factors were investigated for their association to malnutrition in children: “demographic characteristics”, “access to food”, “maternal and child-care practices”, and “poor water/sanitation and inadequate health services”.
Results
A total of 126 mother-child pairs participated in this study and valid data from 109 pairs were subjected to analysis. The rates of wasting, stunted growth, and underweight children were 20.2%, 61.5% and 42.2%, respectively.
Incomplete vaccination (p=0.043) and the mother not having a partner (p=0.046) were significantly associated with wasting. Stunted growth was found to be associated with older child's age (p<0.001), older mothers' age (p=0.005), mothers who had stopped breast-feeding (p=0.031), insufficient breast-feeding (p=0.032), mothers with child death experience (p=0.022), mothers with a number of delivery experiences (p=0.026) and mothers with a partner (p=0.042). Underweight children were associated with incomplete vaccination (p=0.043) and mothers with child death experience (p=0.046).
Conclusion
In total, 8 factors were found to be significantly associated with child's malnutrition and household/family level. In particular, severe acute malnutrition, or wasting, was related to insufficient vaccination, while chronic malnutrition, or stunted growth, was significantly associated with breast-feeding.

Approximately 40% of women during the course of their menstrual cycles suffer from premenstrual syndrome (PMS). The cause of this syndrome is unknown, furthermore diagnostic criteria and treatments have not been established. Kampo medicines were applied using Kami-shoyo-san as a first choice, and several other alternative Kampo medicines, to 33 PMS patient cases. To evaluate the effectiveness of this therapy, PMS scores were recorded prior to treatment. Patients' scores were recorded as; score 0 (symptomless), score 1 (endurable), score 2 (unbearable without medicine), as well as the five major characteristics of PMS, 1) psychiatric symptoms, 2) headache, 3) breast pain, 4) swelling, 5) lower abdominal pain or lumbago. The scores were verified subsequent to two menstrual cycles. Kampo medicine was found to be effective in 24 cases, with scores declining in average from 4.4 to 1.5. Further treatments were requested in 4 cases, moreover, 5 cases were discounted altogether. Thus Kampo medicine proved to be a very useful method for patients suffering from PMS.

OBJECTIVESCancer screening has become common in Japan. However, little is known about the socioeconomic factors affecting cancer screening participation. This study was performed to examine the association between socioeconomic status and cancer screening participation in Japanese males.
METHODSUsing the data of 23,394 males sampled from across Japan, the associations between self-reported participation in screenings for three types of cancer (i.e., stomach, lung and colon) and socioeconomic variables, including marital status, types of residential area (metropolitan/nonmetropolitan), household income, and employment status, were examined using multilevel logistic regression by age group (40 to 64 and ≥65 years).
RESULTSThe cancer screening participation rates were 34.5% (stomach), 21.3% (lung), and 24.8% (colon) for the total population studied. Being married, living in a nonmetropolitan area, having a higher income and being employed in a large-scale company showed independent associations with a higher rate of cancer screening participation for all three types of cancer. Income-related differences in cancer screening were more pronounced in the middle-aged population than in the elderly population, and in metropolitan areas than in nonmetropolitan areas.
CONCLUSIONSThere are notable socioeconomic differences in cancer screening participation in Japan. To promote cancer screening, socioeconomic factors should be considered, particularly for middle-aged and urban residents.

OBJECTIVESTo elucidate the association between genetic polymorphisms ofCYP2a6 andCYP2E1 and urothelial cancer susceptibility.
METHODSA total of 137 Japanese patients with urothelial cancer and 217 Japanese healthy controls, frequency-matched for age and gender, were selected. The polymorphisms ofCYP2A6 andCYP2E1 were analyzed by PCR-RFLP, and cigarette smoking histories were obtained through interviews
RESULTSThe frequency ofCYP2A6 homozygote deletion genotype was 2.9% in the patients, compared with 3.2% in the controls (OR=0.84, 95% CI 0.24-2.96). The frequencies ofCYP2E1 C1/c2 andC2/c2 were 27.7% and 4.4% in the patients, compared with 35.5% and 6.0% in the controls (OR=0.68, 95% CI 0.42-1.09, OR=0.67, 95% CI 0.24-1.84, respectively). No statistically significant differences were observed when theCYP2A6 homozygote deletion genotype and theCYP2E1 genotypes were examined relative to smoking status.
CONCLUSIONSOur data indicate that neither a relationship between genetically impaired nitrosamine metabolism and tobacco-smoking consumption, nor urothelial cancer risk related to theCYP2A6 deletion genotype andCYP2E1 Rsa I genotype was found in Japanese population.

OBJECTIVESGlutathione S-transferase (GST) A1 catalyses the activated heterocyclic aromatic a mine carcinogenN-acetoxy-2-amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (N-OAc-PhIP). This case-control study was carried out to examine whether the genetic polymorphism of GSTA1 is associated with the risk oforal squamous cell carcinoma among Japanese people in relation to their smoking status.
METHODSIn this study, 97 Japanese oral squamous cell carcinoma patients and 457 healthy controls were compared for the frequencies of theGSTA1 genotypes ((*) A:-567T,-69C,-52G,(*) B:-567G,-69T,-52A).
RESULTSThe frequencies ofGSTA1 (*)A/(*)B+(*)B/(*) B genotypes were 32.3% in male cancer patients and 11.4% in female cancer patients, compared with 20.1% in the male control group (Odds ratio (OR)=1.86; 95% confidence interval (CI) 0.99-3.46) and 23.1% in the female control group (OR=0.58; 95% CI 0.18-1.81). TheGSTA1 (*)A/(*)B+(*)B/(*) B genotypes were associated with an 86% increased risk of oral squamous cell carcinoma among males, albeit without statistical significance. Also, among male smokers, the frequency ofGSTA1 (*)A/(*)B+(*)B/(*) B genotypes was significantly higher among the oral squamous cell carcinoma patients (33.3%) than among the controls (19.6%). The OR of the male smokers with theGSTA1 (*)A/(*)B+(*)B/(*) B genotypes for oral squamous cell carcinoma was 1.97 (95% CI 1.02-3.79).
CONCLUSIONSWe present the first evidence of an association betweenGSTA1 (*) B and oral squamous cell carcinoma among smokers. This study suggests that the GSTA1 polymorphism and tobacco smoke-derived PhIP are associated with oral squamous cell carcinoma susceptibility among male smokers.

OBJECTIVE: Suvorexant is a novel hypnotic drug that does not interact with the conventional γ-aminobutyric acid (GABA)-A receptor. We investigated the method by which suvorexant was introduced in insomnia patients who were taking benzodiazepine receptor agonists (BzRA). METHODS: This was a retrospective study. We extracted clinical data for patients who were prescribed suvorexant and were already using BzRA. The patients were assigned to two groups, the switching and add-on groups. We assessed the suvorexant discontinuation rate at one month after the prescription of the drug. RESULTS: One hundred and nineteen patients were assigned to the switching group, and 109 were assigned to the add-on group. The add-on group exhibited a significantly higher all-cause discontinuation rate than the switching group (odds ratio, 2.7; 95% confidence interval, 1.5 to 5.0; adjusted p < 0.001). Intolerability was a significantly stronger risk factor for suvorexant discontinuation in the add-on group (22.0% vs. 7.6%, p < 0.002), and the most common adverse effect was oversedation. CONCLUSION: Our results show that the add-on of suvorexant increases the frequency of oversedation compared with switching in insomnia patients that are taking BzRA. However, this was only a preliminary retrospective study, and further studies will be required to confirm our findings.

In Japan, drug therapy for schizophrenia is characterized by high-dose antipsychotic polypharmacy, which is an uncommon approach internationally. In this study, we reduced the number of antipsychotic agents in 5 patients using the Safety Correction of High-dose Antipsychotic Polypharmacy (SCAP) method and conducted a survey regarding treatment satisfaction. The switch from polypharmacy to monotherapy was achieved in all patients. There was no deterioration in psychiatric symptoms, and adverse reactions were reduced. Three of the subjects were satisfied with the decrease in the number of antipsychotic agents and dose-reduction. These results suggest that the SCAP method is a safe and useful method that can be applied in a clinical setting.

OBJECTIVESThe Community Health Act came into effect in 1997 in Japan. This act altered the work system for public health nurses (PHNs) in public health centers (PHCs) nationwide from region-specific to service-specific work. Such major changes to working environment in the new system seem to be exposing PHNs to various types of stress. The present study examined whether prevalence of burnout is higher among PHNs in charge of mental health services (psychiatric PHNs) than among PHNs in charge of other services (non-psychiatric PHNs), and whether attributes of emergency mental health care systems in communities are associated with increased prevalence of burnout.
METHODSA questionnaire including the Pines burnout scale for measuring burnout was mailed to 525 psychiatric PHNs and 525 non-psychiatric PHNs. The 785 respondents included in the final analysis comprised 396 psychiatric PHNs and 389 non-psychiatric PHNs.
RESULTSPrevalence of burnout was significantly higher for psychiatric PHNs (59.2%) than for non-psychiatric PHNs (51.5%). When prevalence of burnout in each group was analyzed in relation to question responses regarding emergency service and patient referral systems, prevalence of burnout for psychiatric PHNs displayed significant correlations to frequency of cases requiring overtime emergency services, difficulties referring patients, and a feeling of "restriction".
CONCLUSIONSPrevalence of burnout is high among psychiatric PHNs, and inadequate emergency mental health service systems contribute to burnout among these nurses. Countermeasures for preventing such burnout should be taken as soon as possible.
